首先看一下 Fragmen的生命週期如圖所示

Fragment調用的方法以及說明

方法名    說明
onAttach ()                      Fragment被附加到Activity的時，調用此函數，在這個方法中可以獲得宿主Activity。
onCreate ()    Fragment被創建的時，調用此函數。
onCreateView ()    Fragment的佈局加載時，調用此函數。
onActivityCreated ()        當宿主Activity啓動完畢後，調用此函數。
onStart ()                         啓動Fragment時，調用此函數。
onResume ()    Fragment恢復時，調用此函數。
onPause ()                        Fragment暫停時，調用此函數。
onStop()                            Fragment停止時，調用此函數。
onDestroyView()             銷燬Fragment中的View控件時，調用此函數。
onDestroy() 銷燬Fragment時，調用此函數。
onDetach()    Fragment從Activity脫離時，調用此函數

        for (int i=1;i<=5;i++){
            Fragment fragment = new pagerFragment();
            Bundle bundle = new Bundle();
            bundle.putInt("arg",i);
            fragment.setArguments(bundle);
            list.add(fragment);
        }
        MyFragmentAdapter ma =new MyFragmentAdapter(getSupportFragmentManager(),list,title);
        vp.setAdapter(ma);//調用適配器
        pst.setIndicatorColor(getResources().getColor(R.color.colorAccent));
        pst.setIndicatorHeight(5);//條的高度
        pst.setTextColor(getResources().getColor(R.color.colorPrimary));//文字顏色
        pst.setTabBackground(R.mipmap.ic_launcher);//文字背景圖片
        pst.setShouldExpand(true);//是否平分
        pst.setViewPager(vp);

     }
}

News新聞類

<span style="font-size:12px;">public class News implements Serializable {
    private int img;
    private String title;
    private String pubDate;
    private String from;
    public News(){}
    public News(int img, String title, String pubDate, String from) {
        this.img = img;
        this.title = title;
        this.pubDate = pubDate;
        this.from = from;
    }

    public int getImg() {
        return img;
    }

    public void setImg(int img) {
        this.img = img;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getPubDate() {
        return pubDate;
    }

    public void setPubDate(String pubDate) {
        this.pubDate = pubDate;
    }

    public String getFrom() {
        return from;
    }

    public void setFrom(String from) {
        this.from = from;
    }

}</span>

實現方法是：首先創建新聞類然後創建ListView，將一條條新聞放進去，之後將ListView放入到ViewPager裏面，然後將在每一個Fragment都放入一個ViewPager這樣進行調用，並用PagerSlidingTabString實現連動與翻頁，常見的例子很多，這個方法也很實用。
